The Gigabots Go to School

On Monday, July 21st, The Gigabots made a small trip to North Kansas City to visit the First Robotics team at Staley High School. The group of twenty five students—from freshmen to seniors—first had the opportunity to play with with our bots, Prime and Hans, using tablets. Camilla, however, had been disassembled since her trip to New York. The students separated into a few groups, divided up tasks, and quickly rebuilt her.

Students Learning about The Gigabots

After successful bot reconstruction, Jonathan presented a Super Awesome Guide to Programming to the students, in order to teach some basic principles to the majority of the students who had little to no coding experience. He also covered some basics of the JavaScript language, which lead the way directly into programming the Gigabots.

Within minutes, the students, having learned some basic JavaScript, were able to program the connected Gigabots remotely by using the console-based text editor of our Gigabots Dashboard. They started with simple API calls to make the bots beep, buzz, and even sing “Bicycle Built for Two” (the first song ever sung by a computer, in 1961), which quickly became a bit too popular…Other commands moved the bot motors in a similar manner, all remotely and in realtime.

Students then learned how to implement the touch sensor into programming robot behaviors. When the touch sensor button was pressed on the specified bot, for example, the bot would beep, or it would sing, or certain motors would move. They were able to easily create any combinations of responses they could think of and then test them out.

Special thanks to the Staley High School Engineering department and engineering teacher Aaron Dalton for helping to arrange this pilot as well as the students of the Staley First Robotics team for joining us!


The Gigabots Prepare for Upcoming Presentations

In the past two weeks, the dashboard has grown more powerful than ever before.  Its console-based text editor can now make use of the Gigabots API, meaning you can control the Gigabots with simple commands, for a start. More importantly, you can even program larger routines by using multiples of these commands together. In addition, the dashboard’s control panel is more flexible and runs more efficiently.

It’s fun controlling a robot from your phone or computer, but what about when you want to tune into another bot? You can now select a different Gigabot from a drop-down list of bots currently running. Your dashboard instantly updates to the dashboard seen by other users controlling this same bot, and you’ll start receiving its telemetry now instead.

The Gigabots have flown to Silicon Valley this week for the US Ignite Application Summit. We’ll be presenting on Thursday at 11:15 am on the main stage as part of the morning session, ‘Advanced Wireless: Untethering Your Gig.’

US Ignite App Summit

If you’re not in Silicon Valley, you can check out The Gigabots at the fourth annual Kansas City Maker Faire at Union Station this weekend. Come visit us there, at the Mozilla booth, between 10am and 6pm on Saturday, June 28 or between 10am and 5pm on Sunday, June 29.

Kansas City Maker Faire

We’re building two new robots this week, so that Gigabot Prime, our flagship bot, has some more friends to play with. We’re also preparing some demos, so our Gigabots all have things to do, albeit play and work, which they equally enjoy.


Introducing The Gigabots Dashboard

We have been connecting Gigabots to the Internet for a few weeks now. While the robots are overjoyed to send and receive raw data, humans demand more.  As a result, we have created The Gigabots Dashboard, a user interface for controlling Gigabots and receiving realtime telemetry.

We’ve developed the Dashboard with an excellent JavaScript framework named Phaser. Phaser is typically used to create 2D games, but we felt it would be an excellent fit for this project.  One of the benefits of Phaser is our ability to write the application entirely in JavaScript, which allows us to iterate quickly.

Phaser is pretty sweet.

Phaser is also widely used on mobile devices, tablets, and desktops. This gives us confidence it will “just work” everywhere, leaving us more time to add features and change batteries.

Our first attempt at the dashboard was a bit rough,  but it contained most of the core remote-control and telemetry functionality.  After adding a few lines of code to connect the Dashboard to Big Bang, we fired up Gigabot Prime, our first LEGO Mindstorms EV3 robot,  and we were connected.

As expected, we quickly found many areas to improve on for a second version of The Gigabots Dashboard. To more easily control a wheeled Gigabot, there is now a feature to group multiple motors together and control them as a single unit. The Dashboard is also more device-friendly, with keymaps for desktops, and touch controls for mobile devices and tablets.

The team has enjoyed developing the Dashboard and the custom firmware.  We even got to experience a rare moment of “it-just-worked-the-first-time” when connecting the V1 dashboard to the V1 firmware.  We probably should have saved this luck for later.

This week we will start working on APIs that allow Gigabots to be programmed directly in browser.  This will hopefully bring a lot of fun and instant feedback to robotics programming.
